@ Kzhtoo...
i've owned your preamp in the past as well as the Wyred DAC2. depending on the gain in your system and your listening levels, my guess is that you're going to have a very hard time replacing the pass labs preamp with any of these - especially if your system is reasonably revealing and you listen at average to low levels. these matters are SO VERY system dependent, it's impossible to know, but that's my guess. please post back with your findings.
i have - for now at least - given up on the idea of replacing my 2 channel preamp with a DAC offering volume control, although some of the empirical audio offerings look really good in that regard; i'm presently awaiting delivery of an Octave and Audiophilleo interface.
